To all whom it may concern:

Be it known that I, ALEXANDER SPENCER, 1

a subject of the Kingof Great Britain and Ireland, residing atLondon, England, havein vented Improvements in Antifric tion M6Cll'' anism for railway wagons and other vehicles;

of the kind in which the load is transmitted to the running wheel axles through large antifrietion wheels resting upon the end portions or journals of the running wheel axle.

In this kind of mechanism as heretofore usually constructed,-for each running wheel journal two large antifriction wheels are arranged one at each side of the hornplates between which the corresponding bearing s ring extends. The bearing box for the siort axle of these antifriction wheels is formed with laterally projecting flanges which extend between strap plates, between which also extend laterally .projectingflang'es of the plate carrying the bearingsprlng with its buckle, these strap plates forming the connection with the guide or axle boxof the running wheel axle. The end'portions of'the flanges of the bearing box clearly lit between the corresponding hornplates that guide the box in its vertical movementsg I The construction .and arrangement are such that the short axle of thetpainof large antifriction wheels is firmly held against any tilting movement and when the running wheel journal assumes an; inclined position, as is frequently the case when running, the bearing box of the antifriction wheel axle'is jammed either between the strap plates or thehorn plates, or both, and the short axle of the antifriction wheels is strained, the

antifriction wheels running less freely than would otherwise be the case; the load moreover is no longer equal on each antifriction Wheel of the pair.

Now this invention has for object to'provide mechanism of this ty e in which'this disadvantage is obviated. the bearing box of the antifriction wheel axle is arranged to rock between the straps of the axle journal guide box and between the horn plates, relative lateral movement of bearing ox, straps and horn plates, being prevented as heretofore.

Figure 1 of the accompanying illustrative drawings shows partly in front elevation and partly in vertical section corresponding to or this purpose p line A, Ao f-I ig.i 2 one construction of mechanism of the type described, embodying this invention. Fig. 2 is an end elevation thereof partly in cross section corresponding to the line B, B of Fig. 1. Fig. 3 is a detail view hereinafter'referred to.

The upper sides 7c of the lateral flanges m of the bearing box d are curved and thesides n of the flanges m taper off; in a downward di rection as shown in Fig. 3 which is a view of the box d ata right angle to '1, sothat I while at their upper parts the flanges closely fitbetween the horn plates 0, at their lower parts such clearance 0 is left at eachside be tween the flanges and the horn plates that the bearing boxd can rock about the points of contact of the curved upper parts of the flanges with the straight undersides of the to members p of'the straps, clearance being le t between. the flanges'm and the side memmovement.

'As heretofore berszof the straps, as shownytopermit of this usual the bearing boxes (1 may, asshown, be made in'two pieces connected together by bolts passed through the lateral flanges m thereof.

What I claim is .1; Antifriction mechanism for vehicles, comprising a'whee'led axle having journals, antifriction wheels bearing upon said journals and means connecting said antifriction wheels to the vehicle and permitting said antifriction wheels .to rock in relationto the vehicle so that the'axes of the journals and the antifriction wheels willremain-parallel. 2. In antifrictionmechanism, a journal,.a box for said journal, horn plates which guide said box, two relatively large antifriction wheels running on said journal one at each side of said horn-plates, an axle on which said antifriction wheels are mounted, a bearing box for said axle guided by said horn plates, and an abutment for saidbearingbox-connected to said journal box and against which said bearing box can rock.

'3. In antifriction mechanism, a journal, a

box for said journal, horn plates which guide said box, two relatively large antilriction wheels running on said journal one at each side of said horn plates, an axle on which said antifriction wheels are mounted, a bearing box for said axle guided by said horn plates, flanges on said bearing box extending between said horn plates, and an abutment for said bearing box connected to said journal box and against which said bearing box can rock.

4. In antifriction mechanism, a journal, a box for said journal, horn plates which guide said box, two relatively large antifriction wheels running on said journal one at each side of said horn plates, an axle on which said antifriction wheels are mounted, a bearing box for said axle guided by said horn plates, an abutment against which said bearing box can rock, and strap plates connecting said abutment to said journal box.

5. In antifriction mechanism, a ournal, a box for said journal, horn plates which guide said box, two relatively large antifriction wheels running on said journal one at each side of said horn plates, an axle on which said antifriction wheels are mounted, a bearing box for said axle guided by said horn plates, flanges on said bearing box extending between said horn plates, an abutment against which said bearing box can rock, and strap plates connecting said abutment to said journal box.

6. In antifriction mechanism, a ournal, a box for said journal, horn plates which guide said box, two relatively large antifriction wheels running on said journal one at each side of said horn plates, an axle on which said anti'lriction wheels are mounted, a bearing box for said axle guided by said horn plates, an abutment against which said bearing box can rock, strap plates connecting said. abut ment to said journal box, and flanges on said bearing box extending between said strap plates and said horn plates.

7. In antifriction mechanism, a journal, a box for said ournal, horn plates which guide said box, two relatively large antitriction wheels running on said journal one at each side of said horn plates, an axle on which said antifriction wheels are mounted, a bearing box for said axle guided by said horn plates, an abutment against which said bearing box can rock, strap plates connecting said abutment to said ournal box, and flanges on said bearing box extending between said strap plates and said horn plates, said flanges being curved at their upper sides where they bear on said abutment.

8. In antitriction mechanism, a journal, 11. box for said ournal, horn plates which guide said box, two relatively large antifrietion wheels running on said ournal one at each side of said horn plates, an axle on which said antifriction wheels are mounted, a bearing box for said axle guided by said horn plates, an abutment against which said bear ing box can rock, strap plates connecting said abutment to said journal box, and flanges on said bearing box extending between said strap plates and said horn plates, said flanges being curved at their upper sides where they bear on said abutment and the sides of which taper ofl' in a downward direction.
